Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …

Medical Student Research Symposium

Fear-based disorders, including anxiety and posttraumatic stress disorder, are more prevalent in females than males. Steroid hormones (e.g., estradiol) are involved in fear extinction learning and later recall—a process implicated in the pathophysiology of fear-based disorders. Fear-based disorders commonly emerge during the transition from childhood to adolescence, a period marked by the onset of puberty and a natural increase of steroid hormones. Here, we examined the effects of puberty, sex, and their interaction on extinction recall and underlying neural circuitry in youth. Eighty-five youth (6-17 years, 46% female) completed a two-day Pavlovian fear extinction paradigm while undergoing functional magnetic resonance …

Six-Month Report Assessing The Feasibility And Effectiveness Of Amniotic Membrane Injections In Patients With Short, Anterior, Urethral Strictures, Nicholas Pryde, Jack Vernocke, Aron Liaw, Michael Sessine, Nivedita Dhar

Medical Student Research Symposium

Introduction: Urethral stricture treatment has high recurrence rates and adjunct injectable agents have been explored. Amniotic membranes (AM) promote apoptosis of pro-inflammatory cells, prevent differentiation of pro-fibrotic cells, and decrease scar formation. These tissues generated interest in reconstructive urethral surgery. Thus, we performed urethral dilation combined with micronized AM injection in urethral scar tissue for treatment of urethral stricture.

Materials and Methods: Adult males with strictures ≤12Fr in diameter and ≤2 cm in length, International Prostate Symptom Score (IPSS) ≥11 and maximum flowrate <15 ml/s. Reconstituted 100mg micronized AM was injected at the time of urethral dilation. Primary study end point was anatomical success (≥14Fr by cystoscopy) at 6 months. Secondary end points were questionnaires, flow rate, and post void residual. Outcomes assessed at baseline, 5 days, 14 days, 3 months, and 6 months post-injection. Safety was analyzed.

Results: Ten men, mean age of 52 ± 15 years, were included. There were 7 patients with …
